Today, more and more often used for the installation of water pipes, plastic pipes.This is caused not only by their durability but also good performance.Due to the high thermal parameters, polypropylene pipes are ideal for hot water supply.To connect them together using bonding, crimping sleeves and Welding.The latter species is considered to be the most preferred.But in this case you will need a welding machine for plastic pipes.To learn how to select it, and we'll talk in this article.
little about the features of welding
polypropylene pipes can be installed in a system with several types of welding: butt, socket and spigot.If you have no desire to acquire the coupling and fittings, it is necessary to choose the butt connection method, since it is considered to be the most economical.Of course, you need a machine for welding of plastic pipes.The operating principle of the machine is similar to a soldering iron, so it is sometimes called just that.The device must be connected to the heating pipe ends.Docking is implemented in several ways.The most popular - contact-butt.Its essence lies in the combination of melted ends under pressure.Seam strength in most cases does not yield strength of the pipe.The main condition - to provide a high temperature, so pick a soldering iron must be heated to 250-260 degrees Celsius.
Apparatus for welding of plastic pipes: manual or mechanical?
We all know that the welding equipment provides a permanent connection by heating the surfaces to be treated and further their connection.It is necessary to draw your attention to the fact that the welding equipment for plastic and metal products have a number of features and design differences.Units for polypropylene can be divided into two major groups:
- mechanical equipment - used to create a permanent connection of large diameter pipes, as well as where it is necessary to put more effort;
- manual welding machine - the ideal solution for use in the domestic environment (using this unit can be connected in the pipe diameter does not exceed 12.5 cm).
detail of mechanical equipment
If you are going to earn money for welding, then you definitely should give preference to a professional model.Most of the mechanical equipment for the connection of polypropylene pipes is designed for intensive use, as opposed to manual assembly.The device is a support frame on which is placed the instrument unit and the hydraulic unit.On either side of the device has a half-ring gripper.Grippers mounted inserts between which are necessary for uniform distribution of pressure during connection and alignment.The inner diameter of each insert corresponds to the diameter of the pipe.Working body (heating element) is a molded disc with a special coating.Inside it are placed the heating elements.It is worth noting that the welding of plastic pipes runs with adjustable temperature.Any professional welder is a machine, but it does not say that he does not have a manual machine.This is due to the fact that this device is better suited for large-diameter pipes.
Iron, or manual machine for welding of plastic pipes
Most of us chooses a welder to perform one-time operations.Of course, in the future, this tool useful, but it is unlikely he will be heavily used.The device is called the iron is not just because it is the principle of action is reminiscent of the appliance.The main differences are only in the design.Design implies a hot plate and thermostat.For the comfort of works have a special pen.At the end of the heating plate has two holes, into which is inserted the end of two tubes.The Teflon coating prevents the molten tube to adhere to the plate.
Pay attention to packaging products
When buying a product is very important to pay attention to what equipment is available.All depends on the manufacturer, however, it is possible to identify the main elements which must be present.
If you are going to work with the pipes of a maximum of two diameters, the kit, in addition to the unit may include only the key for tips.Again, this is a very modest equipment, which is not always suitable.If you are an amateur, it's best to give preference kit, which will be tips for working with polypropylene tubes following diameters: 20, 25, 32 and 40 mm, which are the most common.
There is also a complete set.This option is the most expensive, so only very popular with professionals.If you are an amateur, then such equipment is unlikely you will come in handy.And now proceed directly to the criteria by which you want to buy an instrument.
Power Equipment
course, welding machine for plastic pipes must be powerful enough.This parameter determines not only the best possible machining diameter, but also the speed of the work.From this, we can conclude that the larger the estimated amount of work, the higher the power required.
In many cases, the instrument will be sufficient average power of 1.5-2.0 kW.But in most cases it is advisable to use a slightly different approach.He concludes that the diameter of the tube is multiplied by 10. The result is a minimum power required equipment.In this case, the welding of plastic pipes will be held without any problem.It turns out that if you want to solder pipes with a diameter of 50 mm, then 50 x 10 = 500 watts.But it is strongly not recommended to buy a low-power tool, it is better to take with a margin of 20-40%.
Choose manufacturer
When you select should pay attention to the company that manufactures welding equipment.It is worth noting that the welding of plastic - a very responsible occupation, and the quality of the instrument will depend on the connection status and longevity.
by far the best in the Czech Republic makes the soldering company "Daytron."The equipment from this manufacturer has earned worldwide recognition.Distinguishing features: high quality and wide functionality.It should be noted that the solder for welding of plastic pipes from the Czech Republic worth a lot, so a good alternative is the Turkish products.For example, a welder, "Candan" is designed to work with pipes 16-160mm diameter.The quality is very good, and the price - acceptable.
Conclusion
is, in principle, and all you can talk about choosing the right equipment.Remember that welding of plastic can cause burns.For this simple reason for buying the equipment attached to it instructions.If such was not complete, consult with professionals and experienced welders.They tell us how to be carried out welding of plastic pipes.Note, however, it is still desirable and in any event to be read and all of the requirements there - run.Do not forget about it.And all will be well.
